FIELD OF THE DISCLOSURE

The present disclosure relates to the field of plant breeding and, morespecifically, to carrot variety NUN 85192 CAC. The disclosure furtherrelates to vegetative reproductions of NUN 85192 CAC, methods for tissueculture of NUN 85192 CAC and regenerating a plant from such a tissueculture, and also to phenotypic variants of NUN 85192 CAC.

BACKGROUND OF THE DISCLOSURE

The goal of vegetable breeding is to combine various desirable traits ina single variety or hybrid. Such desirable traits may include greateryield, resistance to diseases, insects or other pests, tolerance to heatand drought, better agronomic quality, higher nutritional value,enhanced growth rate and improved root properties.

Breeding techniques take advantage of a plant's method of pollination.There are two general methods of pollination: a plant self-pollinates ifpollen from one flower is transferred to the same or another flower ofthe same genotype. A plant cross-pollinates if pollen comes to it from aflower of a different genotype. Plants that have been self-pollinatedand selected for (uniform) type over many generations become homozygousat almost all gene loci and produce a uniform population of truebreeding progeny of homozygous plants. A cross between two suchhomozygous plants of different lines produces a uniform population ofhybrid plants that are heterozygous for many gene loci. The extent ofheterozygosity in the hybrid is a function of the genetic distancebetween the parents. Conversely, a cross of two plants each heterozygousat a number of loci produces a segregating population of hybrid plantsthat differ genetically and are not uniform. The resultingnon-uniformity makes performance unpredictable.

The development of uniform varieties requires the development ofhomozygous inbred plants, the crossing of these inbred plants to makehybrids, optionally three-way hybrids, and the evaluation of the hybridsresulting from the crosses. Pedigree breeding and recurrent selectionare examples of breeding methods that have been used to develop inbredplants from breeding populations. Those breeding methods combine thegenetic backgrounds from two or more plants or various other broad-basedsources into breeding pools from which new lines are developed byselfing and selection of desired phenotypes. The new plants areevaluated to determine which have commercial potential.

One crop species which has been subject to such breeding programs and isof particular value is the carrot. Carrot (Daucus carota subsp.sativus), is a biennial plant that grows a rosette of leaves in thespring and summer, while building up the stout taproot, which storeslarge amounts of sugars for the plant to flower in the second year. Theflowering stem grows several decimeters (e.g., 60-200 cm) tall, with anumbel of white flowers that produce a fruit called a mericarp.

Carrot is grown as a root vegetable, usually orange in color, thoughpurple, red, white, cream, and yellow varieties exist. It has a crisptexture when fresh. The most commonly eaten part of a carrot is theroot, although the greens are edible as well. It is a domesticated formof the wild carrot Daucus carota, native to Europe and SouthwesternAsia. The domestic carrot has been selectively bred for its greatlyenlarged and more palatable, less woody-textured edible taproot. Carrotsare primarily consumed fresh as snack food, raw vegetable or as saladingredient. Carrots are also popular as cooking vegetable and can befrozen and juiced.

United States is one of the largest carrot producers in the world.Between 1994 and 2014, an average production of 1.4 million pounds ofcarrots were produced in the United States (Food and AgricultureOrganization (FAO)). Carrots are grown year-round in the United Stateswith the highest volume coming from California from December to August.

While breeding efforts to date have provided a number of useful carrotvarieties with beneficial traits, there remains a great need in the artfor new varieties with further improved traits. Such plants wouldbenefit farmers and consumers alike by improving crop yields and/orquality. Some breeding objectives include varying the color, size andshape of the root, disease or pest resistance, yield, suitability tovarious climatic circumstances, and storage properties.

“Yield” means the total weight of all carrot roots harvested per hectareof a particular line or variety. It is understood that “yield” expressedas weight of all carrots harvested per hectare can be obtained bymultiplying the number of plants per hectare times the “yield perplant”.

“Marketable yield” means the total weight of all marketable carrotroots, especially roots that are not split, damaged or diseased,harvested per hectare of a particular line or variety.

“Refractometer % of soluble solids” refers to the percentage of solublesolids in juice of pureed roots (mainly sugar), as defined by the USDA.It is also expressed as ° Brix and indicates sweetness in the roots ofcarrot. Brix can be measured using a Brix meter (also known asRefractometer).

“Uniform throughout the root” refers to a characteristic such as colorbeing identical throughout the entire plant part (e.g., throughout theroot when it is cut in half).

A plant having “all the physiological and morphological characteristics”of a referred-to-plant means a plant showing the physiological andmorphological characteristics of the referred-to-plant when grown underthe same environmental conditions, preferably in the same experiment;the referred-to-plant can be a plant from which it was derived, e.g.,the progenitor plant, the parent, the recurrent parent, the plant usedfor tissue- or cell culture, etc. A physiological or morphologicalcharacteristic can be a numerical characteristic or a non-numericalcharacteristic. In one aspect, a plant has “all but one, two or three ofthe physiological and morphological characteristics” of areferred-to-plant, or “all the physiological and morphologicalcharacteristics” of Tables 1 and 2 or “all or all but one, two or threeof the physiological and morphological characteristics” of Tables 1 and2.

The physiological and/or morphological characteristics mentioned aboveare commonly evaluated at significance levels of 1%, 5% or 10% if theyare numerical (quantitative), or for having an identical degree (ortype) if not numerical, if measured under the same environmentalconditions. For example, a progeny plant or a Single Locus Convertedplant or a mutated plant of carrot variety NUN 85192 CAC may have one ormore (or all) of the essential physiological and/or morphologicalcharacteristics of said variety listed in Tables 1 and 2, as determinedat the 5% significance level (i.e., p<0.05), when grown under the sameenvironmental conditions.

“Distinguishing characteristics” or “distinguishing morphological and/orphysiological characteristics” refers herein to the characteristicswhich distinguish the new variety from the other carrot varieties, suchas the Reference Variety (i.e., are different), when grown under thesame environmental conditions. The distinguishing characteristicsbetween carrot variety NUN 85192 CAC and the Reference Variety aredescribed elsewhere herein and also can be seen in Tables 1 and 2. Whencomparing carrot variety NUN 85192 CAC to other varieties, thedistinguishing characteristics may be different. In one aspect, thedistinguishing characteristics may therefore include at least one, two,three or more (or all) of the characteristics listed in Tables 1 and 2.All numerical distinguishing characteristics are statisticallysignificantly different at p<0.05 between carrot variety NUN 85192 CACand the other variety (e.g., Reference Variety).

Thus, a carrot plant “comprising the distinguishing characteristics ofcarrot variety NUN 85192 CAC” (such as a progeny plant) refers herein toa plant which does not differ significantly from said variety in thedistinguishing characteristics above. Therefore, in one aspect, thedisclosure provides a plant which does not differ significantly fromcarrot variety NUN 85192 CAC in the distinguishing characteristicsabove.

Similarity and differences between two different plant lines orvarieties can be determined by comparing the number of morphologicaland/or physiological characteristics that are the same (i.e.,statistically not significantly different) or that are different (i.e.,statistically significantly different) between the two plant lines orvarieties grown under the same environmental conditions. A numericalcharacteristic is considered to be “the same” when the value for anumeric characteristic is not significantly different at the 1% (p<0.01)or 5% (p<0.05) significance level, using one way Analysis of variance(ANOVA), a standard method known to the skilled person. Non-numerical or“degree” or “type” characteristic is considered “the same” when thevalues have the same “degree” or “type” when scored using USDA and/orUPOV descriptors, if the plants are grown under the same environmentalconditions.

As used herein, the term “variety”, “cultivated carrot” or “cultivar”means a plant grouping within a single botanical taxon of the lowestknown rank, which grouping, irrespective of whether the conditions forthe grant of a breeder's right are fully met, can be defined by theexpression of the characteristics resulting from a given genotype orcombination of genotypes, distinguished from any other plant grouping bythe expression of at least one of the said characteristics andconsidered as a unit with regard to its suitability for being propagatedunchanged.

A “plant line” is, for example, a breeding line which can be used todevelop one or more varieties. A breeding line is typically highlyhomozygous.

“Hybrid variety” or “F1 hybrid” refers to the seeds harvested fromcrossing two inbred (nearly homozygous) parental lines. For example, thefemale parent is pollinated with pollen of the male parent to producehybrid (F1) seeds on the female parent.

“Regeneration” refers to the development of a plant from cell culture ortissue culture or vegetative propagation.

“Vegetative propagation”, “vegetative reproduction” or “clonalpropagation” are used interchangeably herein and mean a method of takinga part of a plant and allowing that plant part to form at least roots,and also refer to the plant or plantlet obtained by that method.Optionally, the vegetative propagation is grown into a mature plant. Theskilled person is aware of what plant parts are suitable for use in themethod.

“Crossing” refers to the mating of two parent plants. The termencompasses “cross-pollination” and “selfing”.

“Selfing” refers to self-pollination of a plant, i.e., the transfer ofpollen from the anther to the stigma of the same plant.

“Cross-pollination” refers to the fertilization by the union of twogametes from different plants.

As used herein, the terms “resistance” and “tolerance” are usedinterchangeably to describe plants that show no symptoms orsignificantly reduced symptoms to a specified biotic pest, pathogen,abiotic influence or environmental condition compared to a susceptibleplant. These terms are optionally also used to describe plants showingsome symptoms but that are still able to produce marketable product withan acceptable yield.

The term “traditional breeding techniques” encompasses herein crossing,selfing, selection, doubled haploid production, embryo rescue,protoplast fusion, marker assisted selection, mutation breeding etc. asknown to the breeder (i.e., methods other than geneticmodification/transformation/transgenic methods), by which, for example,a genetically heritable trait can be transferred from one carrot line orvariety to another.

“Backcrossing” is a traditional breeding technique used to introduce atrait into a plant line or variety. The plant containing the trait iscalled the donor plant and the plant into which the trait is transferredis called the recurrent parent. An initial cross is made between thedonor parent and the recurrent parent to produce a progeny plant.Progeny plants which have the trait are then crossed to the recurrentparent. After several generations of backcrossing and/or selfing therecurrent parent comprises the trait of the donor. The plant generatedin this way may be referred to as a “single trait converted plant”. Thetechnique can also be used on a parental line of a hybrid.

“Progeny” as used herein refers to a plant obtained from a plantdesignated NUN 85192 CAC. A progeny may be obtained by regeneration ofcell culture or tissue culture or parts of a plant of said variety orselfing of a plant of said variety or by producing seeds of a plant ofsaid variety. In further aspects, progeny may also encompass plantsobtained from crossing of at least one plant of said variety withanother carrot plant of the same variety or another variety or(breeding) line, or with wild carrot plants. A progeny may comprise amutation or a transgene. A “first generation progeny” or is the progenydirectly derived from, obtained from, obtainable from or derivable fromthe parent plant by, e.g., traditional breeding methods (selfing and/orcross-pollinating) or regeneration (optionally combined withtransformation or mutation). Thus, a plant of carrot variety NUN 85192CAC is the male parent, the female parent or both of a first generationprogeny of carrot variety NUN 85192 CAC. Progeny may have all thephysiological and morphological characteristics of variety NUN 85192 CACwhen grown under the same environmental conditions. Using commonbreeding methods such as backcrossing or recurrent selection, mutationor transformation, one or more specific characteristics may beintroduced into said variety, to provide a plant comprising all but 1,2, or 3 or more of the morphological and physiological characteristicsof carrot variety NUN 85192 CAC.

The terms “gene converted” or “conversion plant” or “single locusconverted plant” in this context refer to carrot plants which aredeveloped by traditional breeding techniques, e.g., backcrossing or viagenetic engineering or through mutation breeding, wherein essentiallyall of the desired morphological and physiological characteristics ofthe parent variety or line are recovered, in addition to the one or morecharacteristics introduced into the parent transferred into the parentvia e.g., the backcrossing technique (optionally including reversebreeding or reverse synthesis of breeding lines). It is understood thatonly the addition of a further characteristics (e.g., addition of geneconferring a further characteristic, such as a disease resistance gene),but also the replacement/modification of an existing characteristics bya different characteristic is encompassed herein (e.g., mutant allele ofa gene can modify the phenotype of a characteristic).

Likewise, a “Single Locus Converted (Conversion) Plant” refers to plantsdeveloped by plant breeding techniques comprising or consisting ofmutation and/or by genetic transformation and/or by traditional breedingtechniques, such as backcrossing, wherein essentially all of the desiredmorphological and physiological characteristics of a carrot variety arerecovered in addition to the characteristics of the single locus havingbeen transferred into the variety via the backcrossing technique, orwherein the morphological and physiological characteristic of thevariety has been replaced/modified in the variety. In case of a hybrid,the gene may be introduced in the male or female parental line.

“Average” refers herein to the arithmetic mean.

The term “mean” refers to the arithmetic mean of several measurements.The skilled person understands that the appearance of a plant depends tosome extent on the growing conditions of said plant. Thus, the skilledperson understands suitable growing conditions for carrot variety NUN85192 CAC. The mean, if not indicated otherwise within this application,refers to the arithmetic mean of measurements on at least 10 different,randomly selected plants of a variety or line.

The relatedness can, for example, bedetermined by fingerprinting techniques (e.g., making use of isozymemarkers and/or molecular markers such as Single-nucleotide polymorphism(SNP) markers, amplified fragment length polymorphism (AFLP) markers,microsatellites, minisatellites, Random Amplified Polymorphic DNA (RAPD)markers, restriction fragment length polymorphism (RFLP) markers andothers). A plant is “closely related” to carrot variety NUN 85192 CAC ifits DNA fingerprint is at least 80%, 90%, 95% or 98% identical to thefingerprint of carrot variety NUN 85192 CAC. In a particular aspect,AFLP markers are used for DNA fingerprinting (see, e.g., Vos et al.1995, Nucleic Acid Research 23: 4407-4414). A closely related plant mayhave a Jaccard's Similarity index of at least about 0.8, preferably atleast about 0.9, 0.95, 0.98 or more (see, e.g., Shim and Jorgensen,Theor Appl Genet (2000) 101:227-233).

In other aspects, thecarrot plant is a hybrid derived from a seed or plant of carrot varietyNUN 85192 CAC.

For the purpose of this disclosure, the “sequence identity” ofnucleotide sequences, expressed as a percentage, refers to the number ofpositions in the two optimally aligned 25 sequences which have identicalresidues (×100) divided by the number of positions compared. A gap,i.e., a position in the pairwise alignment where a residue is present inone sequence but not in the other, is regarded as a position withnon-identical residues. A pairwise global sequence alignment of twonucleotide sequences is found by aligning the two sequences over theentire length according to the Needleman and Wunsch global alignmentalgorithm described in Needleman and Wunsch, 1970, J. Mol. Biol.48(3):443-53). A full implementation of the Needleman-Wunsch globalalignment algorithm is found in the needle program in The EuropeanMolecular Biology Open Software Suite (see, e.g., EMBOSS, Rice et al.,Trends in Genetics June 2000, vol. 16, No. 6. pp. 276-277).

The disclosure also provides methods for determining the identity ofparental lines described herein, in particular the identity of thefemale line. US2015/0126380, which is incorporated by reference, relatesto a non-destructive method for analyzing maternal DNA of a seed.

Using methods known in the art like “reverse synthesis of breedinglines” or “reverse breeding,” it is possible to produce parental linesfor a hybrid plant such as carrot variety NUN 85192 CAC. A skilledperson can take any individual heterozygous plant (called a“phenotypically superior plant” in Example 2 of US2015/0245570; which ishereby incorporated by reference in its entirety; carrot variety NUN85192 CAC is such a plant) and generate a combination of parental lines(reverse breeding parental lines) that, when crossed, produce thevariety NUN 85192 CAC. It is not necessary that the reverse breedingparental lines are identical to the original parental lines. Such newbreeding methods are based on the segregation of individual alleles inthe spores produced by a desired plant and/or in the progeny derivedfrom the self-pollination of that desired plant, and on the subsequentidentification of suitable progeny plants in one generation, or in alimited number of inbred cycles. Such a method is known fromUS2015/0245570 or from Wijnker et al., Nature Protocols Volume: 9,Pages: 761-772 (2014) DOI: doi:10.1038/nprot.2014.049.
